The microstructural evolution during continuous heating experiments has been studied for two C-Mn steels with carbon contents in the range 0.35 to 0.45 wt pct using optical microscopy, scanning electron microscopy (SEM), and electron probe microanalysis (EPMA). It is shown that the formation of the austenitic phase is possible in pearlite as well as in ferrite regions. Thus, a considerable ...sp.info Microstructural Features of Austenite Formation in C35 and ...The microstructural evolution during continuous heating experiments has been studied for two C-Mn steels with carbon contents in the range 0.35 to 0.45 wt pct using optical microscopy, scanning electron microscopy (SEM), and electron probe microanalysis (EPMA).

A core-to-cladding index difference of 0.4 is easily achieved in a HDCMF, which is an order of magnitude larger than can ...

New steels can enhance the performance of critical parts such as bearings, gear teeth, parts subjected to high and low cycle fatigue. The performance level of any hardened steel is determined by the stress levels at which cracking commences in the grain boundaries.sp.info Effect of prior austenite grain size refinement by thermal ...An interesting manner to reduce the size of martensitic substructure is by reducing the size of the prior austenite grain (PAG). This work analyzes the effect of PAGS refinement by thermal cycling on different microstructural features of as-quenched lath martensite in a 0.3C-1.6Si-3.5Mn (wt pct) steel.sp.info The Influence of Microstructural Characteristics on ...In this study, the effects of different microstructural features, such as ferrite grain size, cementite particle size, and pearlite morphology, on austenite formation in a plain carbon steel (0.165 wt pct C, 1.15 wt pct Mn) during isothermal intercritical annealing treatment have been evaluated.
